AUTOMATIC SCALE.

Specification of Letters Patent.

Patented Oct. 23, 1917.

To all whom it may concern:

Be it known that I, RICHARD J. ZANONE, a citizen of the United States, residing in the city of New Albany, county of Floyd, and State of Indiana, have invented certain new and useful Improvements in Automatic Scales, of which the following is a specification.

This invention relates to automatic scales adapted to Weigh commodities of various classes, such as corn meal, chicken feed, etc., either continuously or intermittently.

An object of this invention is to provide a device of the character described, which shall be economical in construction, accurate in operation, and durable in service.

lVith the foregoing and other objects in view, the invention consists of the novel construction and arrangement of parts illustrated in the accompanying drawing, which forms a part of this specification, wherein is set forth an embodiment of the invention, but it is to be understood that such changes and modifications may be resorted to as come within the scope of the appended claims.

Referring to the drawing wherein similar reference characters designate like parts in the several views Figure 1, is a perspective view of an embodiment of the invention showing the various parts in normal position, z'. e. ready to receive a commodity to be weighed, portions being broken away to show* the construction; Fig. 2, a side view of the upper portion, partly in elevation and partly in section, showing the weighing hopper borne down by a contained weighed portion, the mechanism not being set to automatically release the bottom of the hopper to discharge its contents; Fig. 3, a view similar to F ig` 2, showing the parts in the position assumed in discharging a weighed portion, the mechanism being set to automatically release the bottom of the hopper; Fig. 4, a view similar to Fig. 3, showing the position'of the parts when the weighing hopper rises after being lightened of a portion of its contents, the feed gate remaining closed as long as the bottom of the hopper is held open; Fig. 5, a plan view with the top removed; Fig. 6, Va perspective of the gate locking lever; Fig. 7, a perspective view of the tripping lever; Fig. 8, a perspective view of the feed gate operating lever.

Referring in detail to the drawing the reference numeral -1- designates a frame, preferably constructed of angle iron, suitably braced, and carrying a top -2. A receiving hopper -3- is supported by the top, the downward converging Walls of which lead toa chute --l-. The delivery chute 4c depends through an opening 5 in the top. A gate -6- is pivotally attached to the sides of the chute, the point of suspension being forward of the center of gravity so that the gate tends to close by gravity. The gate closes against the bristles of a brush -7- which is secured to the front of the chute. A scale beam comprising a pair of parallel arms -8, 9- held in spaced relationship by means of transverse bars -10- -11- is pivotally supported, in brackets 12- which depend from the top, by means of pivots -13-. A poise weight -l4 is adapted to be adjusted along one of the arms. A counter balance weight -15- is suitably suspended from the rear of the scale beam. A gate operating lever -16-- is pivotally mounted between two brackets -17, 18, which depend from the top. This lever comprises a relatively long vertical arm -19- and a short horizontal arm -20*. The vertical arm is connected by means of a rod -21- with the gate, the arrangement being such that when the arm 19 is in a normal, or vertical position, thel gate is open, and when it is released the gate closes. The arm 19 is held in its normal position by means of alatch -22- carried on a trip lever -23-, which engages with the upper end of the arm. The latch is pivoted on the trip lever, preferably co-incidently therewith, the rear end restin on a pin -24.-, extended from the side o the lever, the arrangement being such that the latch will rise, to permit the arm 19 to return to its normal position, without raising the lever, but when the lever is raised it carries the latch with it releasing the arm and permitting the gate to close. On the inner side of the transverse bar 10, of the scale beam, is a horizontal projection -25- which comes into contact with the arm 20 of the gate lever and returns it to and maintains it in, its normal position, thus holding the gate open as long as the rear end of the scale beam is depressed. A vertical projection w26- from the bar 10, engages with and raises the rear nel in fixed relationship to the frame positioned below the hopper and means within the funnel adapted to be moved into engagement with said catch to release the bottom.

2. In a scale, a frame, a scale beam pivoted thereon, a hopper suspended from said beam, a hinged drop bottom on said hopper, catches pivotally attached to the sides of the hopper and adapted to engage and retain the bottom in a closed position, a funnel in fixed relationship-to the frame positioned below the hopper and means within the funnel to be moved into position for said catch to contact therewith as the hopper descends and release the bottom.

3. In a scale, a frame, a receiving hopper having a bottom outlet, a gate adapted to close said outlet, a bell crank lever, a rod operatively7 connecting said gate and lever whereby they move in unison, a scale beam, the rear end of said beam adapted to contact with, and depress said lever to open the gate, a weighing hopper suspended from the beam, a closure for said hopper, and means for preventing the opening of the gate while said closure is open.

Il. In a scale, a frame, a receiving hopper having a bottom outlet, a ate adapted to close said outlet, a bell crank lever, a rod operatively connecting said lever and gate whereby they move in unison, a scale beam, the rear end of said beam adapted to contact with, and depress said lever to open the gate, a weighing hopper suspended from the beam, a closure for said hopper, holding means adapted to prevent the opening of the gate and means operable by the closing of said closure to release said holding means. n

5.`In a scale, a scale beam, a weighing hopper suspended from the forward end thereof, a chute for delivering material to said hopper, a gate for said chute, a closure for the hopper, means operable by the rear end of said beam on the downward movement thereof to open said gate, and means for rendering said opening means ineffective while said closure is open.

6. In a scale, aV scale beam, a weighing hopper suspended from the forward end thereof, a chute for delivering material to said hopper, a gate for said chute, a closure for the hopper, means operable by the rear end of said beam on the downward movement thereof to open said gate, means for locking said gate in a closed position, and means controlled by the closing of said closure to release said locking means.

7. In a scale, a scale beam, a hopper suspended from the forward end thereof, a chute for delivering material to said hopper, a gate for said chute, a lever engageable by the rear end of said scale beam on the downward movement thereof, a rod connecting said lever and gate, a detent adapted to engage with said rod when the gate is closed, a closure for said hopper, and means operable by the closing of said closure to release` said detent.

8. In a scale, a scale beam, a hopper suspended from the forward end thereof, a chute for delivering material to said hopper, a gate for said chute, a lever engageable by the rear end of said scale beam on the downward movement thereof, a rod connecting said lever and the gate, a detent adapted to engage said rod when the gate is closedI` a closure for said hopper, a rock shaft mounted on the hopper, operative connections between said closure and said shaft, and an arm extended from the shaft and adapted to be moved into position to engage and release said detent upon the closing of said closure.

9. In a scale, a scale beam, a hopper suspended from the forward end thereof, a chute for delivering material to said hopper, a gate for said chute, a lever engageable by the rear end of said scale beam on the downward movement thereof, a rod connecting said lever and gate, a detent adapted to engage said rod when the gate is closed, a closure for said hopper, and a roclc shaft mounted on the hopper, having arms extended therefrom, one of which is connected with the closure and the other adapted to be moved into position to engage with and ren lease said detent.
